Yes Kevin Marr Snr was Norths president in the late 70's & 80's. I see him each January up at Hawkes Nest. In his eighties but still fit and loves talking about the Bears.

I'm pretty sure Kevin jnr didn't play for Manly. He played plenty of first grade for Norths and finished his career at the Gold Coast. His elder brother Greg played Manly Rugby first grade before playing lower grades at the Bears.
